.DUST-SUBDUEB FOR MOTOR-VEHICLES.

To all who/1a 'it muy concern Be it known that l, Benno Salaires, a subject of the Emperorl oi' Germany, residing at Brunswick2 Gern'iany, have invented certain Improvements in Dust-Subduers tor Motor-Vehicles, of which the following is a specification.

ln order to subdue the dust raised by the wheels of motor vehicles, the latter are sometimes provided with dust collectors in the form ot casings or .tunnels which are arranged behind the wheels and adapted to re* ceive and check the dust and then discharge it through a lateral outlet.

The present invention relates to a device of this kind and consists essentially in the provi-sion of means tor guarding the dust collectors against violent impact with the ground and against consequent injury. This is effected by connecting the dust collector to an arm which is pivoted to the chassis and supported on the wheel axle so as to be turned by the latter for lifting the collector clear of any projection over which the wheel happens to pass. The arm is connected to a dash-pot which prevents a too sudden return of the collector to its normal position.

ln the accompanying drawings the invention is illustrated, Figure l representing a side view of the device as applied to one of the rear wheels of a motor car, Fig. 2, a plan of the same, E ig. 3, a sectional side view of the dust collector, on an enlarged scale, and Fig. e, a sectional trent view ot the same.

The dust collector consists of casing 7 which is arranged behind the wheel so as to receive the dust raised by the latter. The casing is divided into a plurality of cells or passages 7L which check the speed ci the dust by its frictional contact therewith. The passages 7'a open into a collecting chamber 9 whence the dust is discharged through a lateral outlet 10. At the trent of the casi ing 7 a scoop 8 is arranged which projects far into the gap between the ground and the wheel 1l so as to gather up the dust and lead it to the collector. The collector is carried by an arm 3 which is pivoted to the chassis l at 2 and which rests on the wheel axle 6. A wedge 5, which is held on the arm 3 by means of a clamp 4t, is interposed between the axle and the arm so as to take the thrust and so as to enable, by being adjusted on the arm, the normal position of the collector relative to the ground to be Specification of :Letters Patent.

regulated. From this arrangement it follows that the jumping movement of the wheel, ensuing upon the latter passing over a projection on the ground, will cause the arm 3 to turn about its pivot so as to lii't the collector clear of such projection. To prevent the collector from dropping too rapidly into its normal position, the arm 3 is connected by means of a bracket 14: to a dash-pot 16, the latter being pivoted at l5 to the bracket ll and at 1S to the carriage body 1T. Resilient runners Q0 are connected to the sides of the casing 7 so as to take the thrust and deaden the shock of slight contacts which the collector, in spite of the precautions, may have to sustain. A pair of brackets 19, connected to the axle G at opposite sides ot the arm 8, serves as guides for the latter.

An elastic tunnel l2, connected by means oil a tlexible pipe 13 to some chamber in which vacuum is maintained, is mounted on the casing Z so as to be near the wheel ll. Owing to this arrangement, the ino and light dust which generally follows the wheel instead of passing to the collector, will be drawn into the funnel l2 by suction and absorbed.

li claim l. In a dust subduer for motor vehicles, the combination with a dust collector, of an arm to which said collector is connected, said arm being pivoted to the chassis and supported by the wheel axle so as to hold the dust collector normally nearl the ground behind the wheel and so as to lift the collector, owing to the jumping movement of the wheel, clear of any projection over which the wheel may pass, substantially as and for the purpose set forth.

2. In a dust subduer for motor vehicles, the combination with a dust collector, of an arm to which said collector is connected, said arm being pivoted t0 the chassis and supported by the wheel axle so as to hold the dust collector normally near the ground behind the wheel and so as to lift the collector, owing to the jumping movement of the wheel, clear of any projection over which the wheel may pass, and a wedge interposed between the axle and the arm and connected to the latter so that it can be adjusted thereon for regulating the normal position of the dust collector relative to the ground, substantially as set forth.

8. In a dust subduer for motor vehicles,

the combination with a dust collector, of an arm to which said collector is connected, said arm being pivoted to the chassis and supported 'by the Wheel axle so as to hold the dust collector normally near the ground behind the Wheel and so as to lift the collector, owing` to the jumping movement of the Wheel, clear of any projection over which the Wheel may pass, and a dash-pot pivoted to said arin and to the body of the vehicle so as to prevent the collector from returning too rapidly to its normal position, substantially as set forth.

4. In a dust subduer for motor vehicles, the combination with a dust collector arranged behind the Wheel so as to receive and check the dust, an elastic suction funnel mounted on said collector so as to absorb the fine dust following the Wheel, and an arm holding the collector` and pivoted to the chassis, said arm being supported on the Wheel axle so as to be turned by the latter for lifting the collector clear of any proj ection over which the Wheel may pass, substantially as and for the purpose set forth.

5. In a dust subduer for motor vehicles, the combination with a dust collector in the form of a casing arranged behind the Wheel so as to receive and check the dust, a scoop arranged in front of the casing so as to lead the dust into the latter, and an arm holding the collector and pivoted to the chassis7 said arm being` supported on the Wheel axle so as to be turned by the latter for lifting the collector clear of any projection over which the Wheel may pass, substantially as and for the purpose set forth.
